Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

email scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Email & Lifecycle Marketing

Email is the highest-ROI channel in SaaS — when done right. This skill helps you design email sequences that drive activation, retention, and revenue with specific copy you can paste into your email tool.

If ABOUT-ME.md and/or MY-ICP.md exist in the project root, read them before writing emails. The "from" voice should match ABOUT-ME.md Communication Style — emails should sound like the founder, not a marketing department. The content should speak to MY-ICP.md — their pain, their goals, their language.

Core Principles

  • Every email must answer: "Why should I care about this right now?"
  • Behavioral triggers > time-based drips. React to what users DO, not how long they've been around.
  • One email, one goal, one CTA. Multiple CTAs = no CTA.
  • Subject lines determine whether your email is read. Body copy determines whether it's acted on.
  • Unsubscribes are better than spam complaints. Make it easy to leave.

Part 1: Professional Branded Email (Do This First)

Before you send a single marketing email, you need a professional email address. Sending from [email protected] kills credibility. You want [email protected] — and you can set this up for free in under 30 minutes.

The Free Setup (Cloudflare + Gmail)

This is the 80/20 approach. You get a branded email address without paying for Google Workspace or managing an email server.

What you need:

  • A free Gmail account (you probably already have one)
  • Your domain on Cloudflare (free plan works — if your domain is elsewhere, transfer DNS to Cloudflare)

Step 1: Set up Cloudflare Email Routing (receiving mail)

Cloudflare Email Routing forwards [email protected] to your personal Gmail — for free.

  1. Go to Cloudflare dashboard > your domain > Email > Email Routing
  2. Click "Get started" and add a destination address (your Gmail)
  3. Verify your Gmail address when Cloudflare sends the confirmation
  4. Create a route: [email protected][email protected]
  5. Add a catch-all if you want (sends ANY @yourdomain.com address to your Gmail)
